Fan Setting Adjustment
1.
Move the FAN OFF lever to the temperature at
which the fan is to stop to prevent circulation of
cool air.
2.
Move the FAN ON lever to the temperature at
which the fan is to turn ON to circulate warm air.
Manual Fan Switch
For constant fan operation (overriding fan setting
levers), push the FAN switch button in. For fan to
cycle automatically, pull button out.
Limit Setting Adjustment
Move the limit lever to the temperature at which the
high-limit switch will open to stop the burner.
CHECKOUT
When installation is complete, disconnect the fan
motor circuit at the L4064. Turn on power and set
thermostat to call for heat. Burner should come on
and limit controller should shut burner off when
plenum temperature reaches the limit set point. Turn
off power, reconnect the fan switch, turn on power
and again set thermostat to call for heat. The fan
should start when plenum temperature has reached
fan-on setting.
